Native port of SKSELogRedirector plugin family (sysdmp), default off

Three FileMapper variants — Steam SSE, GOG, VR — that redirect
<docs>/My Games/<X> onto a sibling folder so SKSE writes logs to the
right place. Only one applies per game; all default off so the user
opts in to the matching variant.

Layout mirrors game_bethesda: shared static lib in src/common/ with the
QObject base (init/author/version/settings/enabledByDefault/mappings),
three plugin .so subdirs each adding Q_PLUGIN_METADATA + their own
name/description and destFolderName override. Q_PLUGIN_METADATA can
only appear once per .so, hence the split.

Paths preserved verbatim from the upstream .py — including the SSE
variant's "Skyrim.INI" sibling folder, which is intentional: a Skyrim
bug sometimes creates a directory of that name and the redirect makes
SKSE find logs in SSE's docs folder.
